The ultimate geek tattoo could only be a transferable one. It's painless—although beware when peeling off the paper, as you might trap a couple of hairs which for most geeks can be a painful experience. This $7.95 pack from Archie McPhee has missed a trick, though. How about a massive line drawing of Jobs' or Gates' face for your back? Then you can strip off your black software T-shirt and really show your fellow tech fiends how you've suffered in the name of tech. {McPhee via Popgadget]
